Investing in manufacturing capacity is a general tactic of industrial nations. I am of course referring to valuable Chinese industry like electric cars, batteries, solar, bullet trains, etc. Just as the USA saw value in stimulating an aerospace industry, China sees value in stimulating a broad manufacturing base and expertise on energy related production. My claim is that this isn’t unfair, this is standard industrial policy. Except the USA has literally forgotten the value of industrial policy so when someone does it properly we misinterpret it as cheating.
